Motor cycle Helmets


Why Helmets should be worn while riding bike:

A safety helmet is one of the most important items of personal protective equipment used by motorcycle riders primarily to protect the head against impact. Helmets won't prevent accidents, but they clearly will cut down on deaths and injuries when collisions occur.


No matter what your age or level of experience, whenever you ride a bike helmet should be worn. In fact, many states now have laws that require helmet use.

Wearing a bike helmet reduces the risk of serious head and brain injury by 85%. Helmets should be worn during every ride, no matter how short. Many accidents happen near home.

Facts about Helmet:
Ø  It should not obstruct vision.
Ø  It should not impair with hearing.
Ø  It should not heavy weight.
Ø  It should not cause fatigue which causes crashes.
Ø  It should not cause skin diseases.
Ø  It should not increase the probability of neck injuries

Kinds of helmets to be used:
It should have a thick padding of thermo Cole - at least 20 mm- which must extend to the sides of the head. A full face helmet is safer by all means.

Fit: Make sure that the size and shape of the helmet are suited to your head.

Comfort : Make sure the helmet is as comfortable to wear as possible

Components of the helmet and their roles

The shell :-
The shell of a helmet is an injection moulded thermoplastic or a pressure moulded thermoset that is reinforced with glass fibers or made of fiber glass

* It absorbs energy in an impact : The shell bends when the helmet is impacted and the underlying foam deforms. At ,moderate speeds the shell can take one-third of the impact energy.

* It distributes local forces from an impact : Rigid objects like stone or a projecting beam can cause a skull fracture at low forces, the shell acts to distribute the force of such impact eliminating the risk of penetration.

* It allows sliding on road surface : The shell being rigid and having a convex shape allows the helmet to side along a road surface without there being an excessive force.

* It protects the face and temples : Full-face helmet is beneficial in protecting the face and jaw. The chin bar of such helmets contain rigid foam to absorb energy for direct blows on the chin, prevent facial bone fractures and prevent the lower part of the forehead and temple being struck.

The Foam Liner :-

This is a moulding of polystyrene beads or polyurethane foam. It provides a stopping distance for the head. The foam can compress by 90% during an impact, although it recovers partially afterwards. But this helps increase the stopping distance thus reducing the peak deceleration of the head. It  also protects as much as possible of the head.

 Proper strapping system :-
It is essential to wear a well-fitting helmet for the effective working of chinstrap system. To test if the helmet fits your head properly, tightly fasten the chinstrap and then pull helmet off forward by gripping the rear and then pulling. The strap must be threaded correctly so that the buckle locks the strap when  it is pulled from the chin side. The strap must be pulled as tight as is bearable under the chin.

Replacing of helmets :-  

* Helmet should replace once in a three years (doesn't matter it may looking good in appearance and condition)

* Replace the helmets in case if the helmet got hit / met any accidents.

* Replace the helmets which having any kind of damages (shell. foam liner, chinstrap)
